AUTOMATIC DUMPING-GAR.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed March 28, 1906. 7 Serial No. 308,462.

To all whom it may concern:

Be it known that 1, JAMES WILLIAM REED, a citizen of the United States, and a resident of Berwind, in the county of Las Animas and State of Colorado, have-invented a new and Improved Automatic Dumping-Car, of which the following is a full, clear, and exact description.

. This invention is an improvement in automatic dumping cars more especially designed for hauling coal, but can be used with advantage for hauling ore, dirt or other desired material.

One 'of the objects of the invention is to provide a car which can be dumped and closed up automatically, thereby dispensing with the labor, time and expense usually entailed when these operations are performed by hand.

It has for a further object, to provide means fixed near the track at a point where the car is to be constantly dumped, to perform the dumping and closing of the car while the car is in continued motion on the track.

'Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the car and track; Fig. 2 is a plan view of the car in inverted position; Fig. 3 is a transverse section on the line 33 of Fig. 2; Fig. 4 is a detail of the locking and unlocking means for the car sides; andFig'. 5 is a plan view of the rail and showing the position of the cams for opening and closing the car sides.

The numeral 1 indicates a railway track carrying a car 2 having sides 3, and fixed end portions 4. Hingedly attached to the sides 3 are side portions 5, ada ted to be. swung outwardly when release from upturned fingers 6 on a locking bar 6 held to rock on a bottom frame of the car. body. The

bottom 7 of the'car 2 is inclined from its 7 longitudinal center downwardly to the lower edges of the pivotally mounted side portions 5, and has attached at its transverse center at each side of the longitudinal center, inclined portions 8, shown in Figs. 1 and 2. rovides a car bottom which will empty its oad with certainty when the hinged side portions 5 are opened. The side edges of the car bottom 7 are riveted or otherwise secured to side plates 9 running the entire length of the car. To both sides and at each end of the car is secured an angular bar 10spaced from the plates 9 and forming supporting side frames for the car journals an supporting bearings for the ocking bars 6 and brake shaft 11. Each angular bar 10, as shown best in Fig. 1, consists of a series of horizontal and inclined portions, the horizontal portions for the purpose of seating bearings 12 and journal boxes 13, and securely clamping them against the plates 9 by means of bolts 14 fitting closely at each side of each bearing and journal box. Secured between the plates 9 and bar 10,at each end thereof, is a pair of parallel transverse bars 15 carrying bumpers 16 and an intermediate coupling bar 17, having couplers 18 at each end.

In the journal boxes 13 rotate the journals carried at the ends of axles 19, upon which wheels 20 are fixed. Between the wheels 20 bearings 11 are secured on the bars 10, car.- rying the brake shaft 11 that is provided with brake shoes 21 secured to each end for contacting -with the tread. of the wheels. Fixed to the brake shaft is a bifurcated arm 22 connected to a link 23, which at one end is connected to a chain 24 attached to the lower end of a lever 25 pivotally mounted on a pin 26. The lever 25 passes through a slotted and curved bracket 27 fixed at one endof the car, having teeth 28 with which a pro jection on the lever is adapted to engage when desired to lock the shoes 21 The link 23 passes through the bifurcated arm 22 and is pivotally attached thereto by having its end bent at right'angles and inserted therethrough, said link is engaged in the bifurcation of the arm by one end of a spring 29 held at its opposite end on one of the locking bars 6. By this construction the brake shoes can be easily applied to the wheels by turning the lever 25 on its pivot 26 and held in this position by the rack teeth 28 engaging the lever and released by the spring 29 when the bar and teeth are disengaged.

Secured to the bottom of the car, as best shown in Fig. 3, is a sheet metal support 30 with downwardly-bent Wings 31 at each side. One pair of said wings are for pivotally supporting an L-shaped lever 32 at 33 and the other pair for forming guides for the horizontal end of said lever. Attached to one side of the car and to a downwardly-extendagainst the wheels.

ing arm of the lever 32, is a spring 34 for holding the horizontal portion of the lever 32 ing bar 6, said arm 35 having a portion 36extending below the locking bar for a purpose hereinafter described. Adjustably secured to the arm 35 by means of a pin 38 is a link 37 having bifurcations at each end provided lever 32 out of the path of the arm 35, the

projecting arm 36 may be operated to turn 5 the locking bars 6 in their bearings, thereby Y disengaging the locking from the hinged portion .allowing the load to slide from the bottom of the car body.

On the track 1 at some fixed point for unfingers 6 thereon loading the car, I provide a block 41 and thin i spring cams 42, 42 and 43, the cams 42 and 42* being fixed near the center of the track and the cams 43 intermediate and at each side thereof. The cams 42 and 42 are slightly S-shaped, as shown in Fig. 5, and are supported by standards 42 and the cams 43 are convex on their opposed faces and are supported on standards 43 to about the height of the center of the hinged side portions 5. The form of the block 41 is best shown in Fig. 1 and has a vertical front face and a J slightlyrounded and tapering back'positioned near the cam 42. By making the cams allof spring metal, they are enabled to yield and take up considerable shock when brought into engagement with the car. 44 is a lever pivoted to one of the ties of the track between the cams 42 and 42, having a handle 44 and carrying hooks 45 at each end, adapted to be projected over the rails, when the lever is turned on its pivot to give the car a jolt as the wheels pass over them in order to positively shake the load 45 from the car bed.

The operation of the unloading mechan-' ism is as follows: Upon moving the loaded car in the direction of the arrow shown in Fig. 1, the vertical portion of the lever 32 engages the cam 42, whereby its upper end is carried out of the path of the arm 35, after which the arm 36 strikes the vertical face of ithe block 41 turning the locking bars 6 in their bearings and the locking fingers 6 from engagement with the side portions 5, permitting the load to slide from the bottom of the car. On the continued movement of the car in the same direction, the hinged side portions 5 are engaged by the spring cams 43 6o pushing them into closed position and at about the same time the arm 36 passes off the block 41 sufficiently to allow the spring 39 through link 37, locking bars 38 and looking fingers 6 to lock the hinged sides 5 in place. The arm 35 is, however, not permit- It is thus apparent that by moving the horizontal arm of the- 5 of the sides and out any manipulation other than the movement of the car on the track.

It is not my intention to limit the invention to the exact details ofconstruction here- 3 inbefore described, but consider that I am entitled to such modifications as fall within a .fair interpretation of the claims.

Having thus described my invention I claim as new and desire to secure by Letters 35 Patent:
